      • CD35
      Background InformationComplement receptor type 1 (UniProt: P17927; also known as C3b/C4b receptor, CD35, CR1) is encoded by the CR1 (also known as C3BR) gene (Gene ID: 1378) in human. CR1 is a single-pass type I membrane glycoprotein that is expressed in most peripheral blood cells, follicular-dendritic cells, Schwann cells, and glomerular podocytes. It regulates the activation of the complement cascade by serving as a cofactor for the factor I-mediated cleavage of C3b and C4b and also accelerates the decay of the C3 and C5 convertases. It is shown to bind to C3b and C4b opsonized immune complex on erythrocytes and transports them to liver and spleen where they are degraded by phagocytes. CR1 inhibits spontaneous complement activation by impairing the formation and function of the alternative and classical pathway C3/C5 convertases, and by serving as a cofactor for the cleavage by factor I of C3b to iC3b, C3c and C3d,g, and of C4b to C4c and C4d. It also plays a role in immune regulation by contributing to the generation of regulatory T cells from activated helper T cells. CR1 is synthesized with a signal peptide (aa 1-41), which is subsequently cleaved off to generate the mature form with a long extracellular domain (aa 42-1971), a short transmembrane domain (aa 1972-1996) and a cytoplasmic tail (aa 1997-2039).
